When I lived in the USA, I once received a card from a co-worker from my birthday. I hung it up on the window of my office along with the other cards from co-workers and clients. I didn't realize that the front of the card had an image of a black man on the front. When I received it I opened up the envelope, quickly opened it and read the inside which had a standard message and thanked my co-worker (who was a black woman). I never noticed that the man on the front of the card wasn't white. As people passed my office and noticed it they made all kinds of comments to me and some of my black co-workers got upset and thought I was making fun of them, and to top it all off the director of human resources called me and asked me to remove the card. Apparently Hallmark had put out a line of greeting cards called "The Mahogany Collection" which have African American themes and is geared towards the black community. I grew up in a mixed nationality (russian / cuban) family and we were constantly labeled, categorized, even made fun of and discriminated and asked billions of questions.
